The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
Here’s how: Count the cells: Most batteries are made up of multiple cells connected in series. Each cell has a nominal voltage. Multiply by the number of cells: Multiply the nominal voltage of a single cell by the number of cells in the battery to get the nominal voltage of the battery.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts.
